Sebastian, a 49-year-old taxi driver, presents to ED following a brief episode of syncope associated with profuse sweating and pallor.

He reports mild chest discomfort, dizziness and having passed dark black stool that morning.

A month previously, Sebastian was diagnosed with oesophageal adenocarcinoma, having presented with a two-month history of progressive dysphagia and 4kg weight loss.

Gastroscopy revealed a mass with stricture effect in the distal oesophagus.
